A creepy stalker story becomes a shrewd whodunit as Saul's latest tracks a move from tranquil suburbia to the big city. After a job promotion, the Marshall family prepares to move from Long Island to Manhattan, unaware that a menace edges ever closer to kidnapping their teenage daughter, Lindsay. Eerie first-person chapters from the stalker's close-call perspective effectively counterpoint parents Kara and Steve Marshall's stressful relocation hurdles, as intuitive Kara begins sensing the imminence of the threat, but meets with resistance from harried family members. After the anonymous menace snatches Lindsay, Saul broadens the scope to encompass four likely male suspects, including a pair of real estate agents (one dour and one impossibly chipper). Steve Marshall conveniently dies in a car accident; police sergeant Andrew Grant is cautious and unconvinced of foul play. Lindsay's attempts to escape and the criminal's master plan keep the tension high and the plot accelerating, making this solid suspense from the veteran author of Suffer the Children and the Blackstone Chronicles series.
